  • Patent number: 9084892
    Abstract: The sound processor and method uses a model of basilar membrane motion to select stimuli, based upon the predicted motion which the acoustic signal presented would produce in an acoustically excited normally hearing cochlea. The filter; used, in contrast to single channel per electrode approaches, cover multiple channels and overlap with each other. Consequently the stimuli presented produce a neural excitation pattern which approximates the spatio-temporal travelling wave observed on the basilar membrane in an acoustically excited normally hearing cochlea. Preferably, the predicted electrode stimuli are based upon the instantaneous predicted amplitude of the electrode location.

  • Patent number: 8260429
    Abstract: In one aspect of the invention, a cochlear implant constructed and arranged to successively generate stimulation signals each comprising at least one stimulus pulse such that said successive stimulation signals incrementally build a neural excitation pattern that accurately reflects a received sound. In one embodiment, each said successive stimulation signal is generated based on the cumulative effect of all previous stimulus pulses, thereby compensating for finite spatial spreading of individual stimulus pulses as well as for the temporal integration of the neural excitation pattern along the neural pathways.

  • Patent number: 8135152
    Abstract: A method and apparatus for detecting an envelope of an audio signal, and a method and apparatus for enhancing the pitch cue of an audio signal perceived by a cochlear implant patient where the audio signal is processed and input to an implant device of the recipient. The methods and apparatuses use techniques such as filtering, rectifying, detecting peak values, sampling, resetting, comparing and multiplying various signals to detect the envelope or enhance the pitch cue of the audio signal.
